Applications
The raceways of angular contact ball bearing in the inner and outer rings can have relative displacement on the horizontal axis. Therefore, this design can make it withstand combined loads, namely, supporting radial and axial loads simultaneously. The axial load capacity of angular contact ball bearing improves with the increasing contact angle.
